Claims.

This invention relates to huller gins. It is an improvement upon a ginof the type disclosed in my Patent No. 2,142,977, granted January 3,

1939, which has an inner ginning breast and an 5 outer huller breast,forming between them a roll box, each breast having a grating of ribswith the gin saws passing between both sets-of ticles, seeds, etc. thatit becomes necessary to i dump the roll from the roll box. In myaforementioned patent, the inner or ginning breast is pivoted at itsupper end to the gin, and the outer or huller breast is pivoted at itsupper end to the inner breast. Thus, both breasts can be swung uncut asa unit at the bottom, to cause the withdrawal oi the saws from betweenboth sets of ribs, and when-it becomes necessary to dump the roll box,the outer breast can be swung out independently of the inner breast,enlargingthe space between the two sets of ribs so'that the roll candrop downwardly through the passage thus formed. The primary purpose ofswinging both breasts out as a unit, so as to withdraw the saws, is toclear ribs of accumulated matter, as well as to get accessto the sawsfortheir replacement or repair It is advantageous, however, to havethebreasts separated from the gin at the time the outer breast isseparated from the inner breast to dump the rollbox, for the saws are[then out 01" the path of the discharged roll.

In my patent, means are provided for separating both breasts at thebottom from the gin, and for separating the outer breast at the bottomfrom the inner breast, and for holding them in separated positions.

One of the disadvantages of a construction in which the huller breastispivotally connected at its top to the ginning breast is that the passagewhich it provides when spread, for the roll, is narrow at the top sothat the roll does not always drop out automatically, but often has tobe started by poking it with a stick.

The general object of the present invention is to-avoid thisdisadvantage by substituting for the translatory movement that shallseparate the outer breast from the inner breast substantiallyuniformboth at the top and at the bottom, so as to -provide a passagefor the discharge of the roll which is much wider at the top than in thecase of an outer breast which operates by separating pivotally from theinner breast. In this connection, reference is here made to my pendingapplication, Ser. No. 259,033, filed February 28, 1939, which disclosesan outer breast movable in a translatory manner with respect to theinner breast,

Another object of the invention is the provision of means for effectingthe separation of the outer breast from the inner breast by bodilytranslatory movement both at the top and at the bottom, and maintainingthe outer breast in such separated position. e

Other objects of the invention will appear as the following descriptionof a preferred and practicai embodiment thereof proceeds.

In the drawings which accompany and form a part of the followingspecification, and throughout the several figures of which the samecharacters of reference have been employed to designate identical parts:t

Figure l is a side elevation of a huller gin embodying the features ofthe present invention showing the inner and outer breasts-in closedposition; and

Figure 2 is a similar view showing the breasts in spread or separatedposition.

Before referring in detail to the figures, it may be statedthat onlysuch features of the huller gin as directly appertain to the presentimprovement are hereinafter referred to, and that those unskilled in theart who may require a more detailed exposition of gin construction foran understanding of the invention, are referred to my Patent No.2,142,977, in which the more detailed explanation of the inner parts maybe found.

The huller gin of the present invention includes the fixed frame I,which carries the saw shaft 2 with the saws 3. The inner breast 4 ispivotally mounted upon the frame I at 28, and normally rests against theframe I, as shown in Figure 1. The outer breast 5 co-operates with theinner breast to form a roll box, the rotary end plate of which isindicated at 6 in Figures 1 and'2. Most of the roll box is definedwithin the walls of the inner breast, but the face I of the outer breastforms the outer wall of the roll box. There is normally a narrow passagefrom the roll box downward between the breasts for the passage ofseed,.when the outer breast 5 is inthe closed position shown in Figure'1. The saws 3 normally intersect this narrow passage cooperating withboth breasts. Both the inner and outer breasts can be swung away fromthe fixed frame I so as to withdraw the saws from the passage betweenthe breasts. This swinging movement is accomplished by means of a togglecomprising the two links 9 and I0 pivoted together at ll, and havingtheir opposite ends l2 and I3 pivoted, respectively, to the fixed frameand to the inner breast. A hand lever l4 operates this toggle. It beingassumed that the inner breast 4 is in closed posi-- tion with respect tothe frame I, the toggle is in the folded position indicated in Figure 1.When the hand lever I4 is thrown in a clockwise direction, the togglestraightens out as shown in Figure 2, spreading the inner breast at thebottom, from the gin.

Instead of the upper pivotal connection for the outer breast, asemployed in the huller gin disclosed in my said patent, the end platesof the inner breast are provided with the track flanges l5, which arepreferably upturned at both ends. The end plates of the outer breast 5are formed with lugs l6 carrying rollers I! which ride upon the trackflanges. Thus, the outer breast rides bodily in or out with respect tothe inner breast for a range of distance represented by the length ofthe track flanges IS. The forward upturned ends I8 of said track flangesconstitute stops to limit the outward movement of the upper end of theouter breast 5. Themovement of the upper part of the outer breast isproduced by toggles, one on each side of the gin, each comprising thetwo links [9 and 20 which are pivoted at their adjacent ends at 2! andat their outer ends, respectively, to the inner breast at 22, and to theouter breast at 23, the latter pivot preferably being the axis of therollers 11. When this toggle is in folded position, the upper part ofthe outer breast is at its extreme limit of outward movement. When thistoggle is straightened, as shown in Figure 1, the rollers ll have beenforced to the innermost limits of their range of movement, and the upperpart of the breast is in closed position.

The means for opening and maintaining open the lower part of the outerbreast are same as in my Patent No. 2,142,977, said means, comprising atoggle consisting of the cooperating links 23' and 24 pivoted at theiradjacent ends at 25, and at their opposite ends, respectively, to theinner breast at 26 and to the outer breast at 21. When said toggles arein folded position, as in Figure 1, the bottom of the outer breast isclosed. When this toggle is in straight position, as in Figure 2,

the bottom of the outer breast is in open position relative to the innerbreast.

Means are provided for synchronizing the opening and closing movementsof the toggles at the top and bottom of the outer breast. Said means inthe present illustrative embodiment of the invention comprises a link 2%connecting the middle pivots of the toggles on one side of the gin. Ahand lever 3| operates the lower toggle, and through the intermediary ofthe link 29, also operates the upper toggle so that when the lowertoggle is straightened to separate the bottom of the outer breast fromthe inner breast, the upper toggle is broken in order to separate theupper part of the outer breast from the inner breast. It will beunderstood that the pivots l2 and 26 to which the respective handlelevers hi and 3| are secured, are in fact rods extending to the oppositesides of the gin, and which operate duplicate sets of toggles, such ashave just been described.

It will be evident from an inspection of Figure 2 that by means of thetrack and roller connection between the outer and inner breasts ashereinbefore disclosed, or by the employment of equivalent mechanicalmeans for accomplishing the bodily separation of the two breasts at thetop, as well as at the bottom, the front face of the roll box is movedaway from the portion of the roll box embraced within the inner breast amuch greater distance than is possible with any pivotal connection, andamply wide to assure the automatic discharge of the roll from the rollbox.

While I have in the above description disclosed what I believe to be apreferred and practical embodiment of the invention, it will beunderstood to those skilled in the art that the details of constructionand the arrangement of parts as shown and described, are to beconsidered by way of example, and not as limiting the invention which isdefined in the appended claims.
